<I>I have heard you and Leo Laporte discuss the merits of 1080p versus 1080i signals. You both agreed that both methods are almost indistinguishable from each other, but neither of you seemed clear as to why they were so close. Well, I believe I may have the reason, but please correct me if I am wrong. The essential feature is their respective frame/field rates. 1080p is 30 true frames or complete pictures per second, whereas 1080i is 60 fields per second, but because it is interlaced, it also results in a true 30 frames per second. Thus, both formats generate the exact same number of true frames or pictures per second, which is why their ultimate picture qualities are identical.
